PROCESS OF FORMING AND A SEAL FOR AN ENGINE
A process of forming a turbine engine seal includes the steps of: providing a flat strip of material; roll forming the flat strip of material forming an asymmetric profile in the flat strip of material; coiling the formed asymmetric profile into an overlapping ring shape; cutting the circular shape to a predetermined length; and joining ends of the predetermined length forming the seal. The seal includes at least two peaks that are formed on opposing sides of a gap. The at least two peaks contact opposing sides of a U shaped profile at a zero radius. The asymmetric profile includes a circular shape and the ends are joined.
COOLING FEATURES WITH THREE DIMENSIONAL CHEVRON GEOMETRY
An internally cooled component of a gas turbine engine is provided. The component may include a cooling passage at least partially defined by a first wall and a second wall with a first pedestal extending from the first wall to the second wall. The first pedestal may have a chevron geometry. A second pedestal may extend from the first wall to the second wall and also have a chevron geometry. A gap may be defined by the first pedestal and the second pedestal with the gap oriented between the first pedestal and the second pedestal.
Aircraft nacelle comprising a deformable connection between an air intake and a power plant
An aircraft nacelle comprising a first duct secured to an air intake and a second duct secured to a power plant. The two ducts are arranged end-to-end and connected by a connection. The connection comprises a bracket which extends between a first region for connecting to the power plant and a second region for connecting to the air intake, and which comprises a J-shaped profile in longitudinal planes, having at least one curved portion offset towards the outside of the nacelle with respect to the connecting regions.
WEAR LINER FOR FIXED STATOR VANES
The present disclosure provides a wear liner for a stator vane that has a first hook and a second hook that are connected by a base, providing in a generally S-shaped channel. The wear liner includes an outer surface that is adapted to lie against a first component and an inner surface that is adapted to lie against a second component. The first hook of the wear liner includes a first engaging end that is adapted to engage a first component, while the second hook is adapted to engage the second component. The first component may comprise a vane foot and the second component may comprise a slot for receiving and securing the vane foot.
ENGINE COMPONENTS WITH COOLING HOLES HAVING TAILORED METERING AND DIFFUSER PORTIONS
An engine component includes a body having an internal surface and an external surface, the internal surface at least partially defining an internal cooling circuit. The component further includes a plurality of cooling holes formed in the body and extending between the internal cooling circuit and the external surface of the body. The plurality of cooling holes includes a first cooling hole with a metering portion with a constant cross-sectional area and a cross-sectional shape having a maximum height that is offset relative to a longitudinal centerline of the metering portion; and a diffuser portion extending from the metering portion to the external surface of the body.
SEAL RING FOR GAS TURBINE ENGINES
An annular ring for sealing a flow includes an inner ring and a tab. The tab extends radially and is configured to restrict axial movement of the seal.
SEAL ASSEMBLY
A seal assembly is disclosed. A seal assembly may comprise a seal carrier, a compliant structure comprising a first end and a second end, wherein the first end is coupled to the seal carrier, and/or a support structure coupled to the second end. The seal carrier may be integral with the compliant structure.
Fuel manifold and fuel injector arrangement for a combustion chamber
Each fuel injector has a main nozzle and pilot nozzle. A main fuel manifold to supply fuel to the main nozzle of each fuel injector and pilot fuel manifold to supply fuel to the pilot nozzle of each fuel injector. The main fuel manifold includes plurality of flexible main fuel pipes. Also, plurality of cross-piece connectors including a stem and four arms. The stem of each connector mounted on one fuel injector. The first and third arms extend in opposite directions from the stem and second and fourth arms extend in opposite directions from the stem. Each fuel pipe interconnects the first arm of one connector with a third arm of an adjacent connector and each connector so the first and third arms are at an angle relative perpendicular to the axis of the annular combustion chamber casing so the main fuel manifold extends around the combustion chamber casing sinusoidally.
Vane arc segment platform flange with cap
A vane arc segment includes an airfoil piece that has a first platform, a second platform, and an airfoil section between the first platform and the second platform. At least the first platform is formed of a fiber-reinforced composite (FRC) and defines a radial flange. A cap is fitted on the radial flange.
Quad-tab U-washer
A washer includes a first lobe comprising a first hole, a second lobe comprising a second hole, a third lobe comprising a third hole, and a fourth lobe comprising a fourth hole. A first leg extends from the first lobe to the second lobe, and a second leg extends between the third lobe and the fourth lobe, wherein the second leg is parallel to the first leg. A third leg extends from the first lobe to the third lobe and spaces the first leg from the second leg such that the second lobe is disposed opposite the fourth lobe.
